Question

which is true about glycolysis?
it has a net yield of 2 atp molecules.
it takes place in the mitochondria.
it requires oxygen.
it takes place in the cell membrane.
rewatch

Explanation:

• For "It has a net yield of 2 ATP molecules": Glycolysis breaks down glucose. In the process, 2 ATP are used and 4 ATP are produced, so net yield is 2 ATP. This is correct.
• For "It takes place in the mitochondria": Glycolysis occurs in the cytoplasm, not mitochondria. So this is wrong.
• For "It requires oxygen": Glycolysis is an anaerobic process (does not need oxygen). So this is wrong.
• For "It takes place in the cell membrane": Glycolysis occurs in the cytoplasm, not cell membrane. So this is wrong.

Answer:

It has a net yield of 2 ATP molecules.
